FIELD OF THE INVENTION

The present invention relates to herbicidal compositions and methods for killing or controlling the growth and proliferation of unwanted plants. The herbicidal compositions of this invention cause early visual symptoms of treatment and/or enhanced effectiveness when applied to the foliage of plants. These compositions comprise N-phosphonomethylglycine, or derivatives thereof, and a bipyridilium or derivatives thereof, with one or more suitable surfactants. The herbicidal compositions found to be useful for this purpose, as well as methods for using them, are described herein.

BACKGROUND OF THE INVENTION

Herbicidal compositions comprising the herbicide N-phosphonomethylglycine or derivatives thereof (“glyphosate”) are useful for suppressing the growth of or killing unwanted plants such as grasses, weeds, and the like. Glyphosate typically is applied to the foliage of the target plant. After application the glyphosate is absorbed by the foliar tissue of the plant and translocated throughout the plant. Glyphosate noncompetitively blocks an important biochemical pathway which is common to virtually all plants, but which is absent in animals. Although glyphosate is very effective in killing or controlling the growth of unwanted plants, the uptake (i.e., absorption) of glyphosate by the plant foliar tissue and translocation of glyphosate throughout the plant is relatively slow. Visual symptoms that a plant has been treated with glyphosate may not appear until one week or more after treatment.

Although early visual symptoms of plant treatment generally can be achieved using compositions comprising glyphosate and the contact herbicide pelargonic acid, such compositions have several drawbacks. First, they require high application rates of the pelargonic acid. Second, they often do not permanently kill plants. Pelargonic acid attacks the plant very rapidly so that the glyphosate may have insufficient time to translocate into the plant and completely kill the plant. This drawback is particularly evident when the compositions are used to treat perennial plants such as, but not limited to, Johnsongrass. Third, the compositions are difficult to prepare in a stable formulation; the formulations frequently settle or solidify. Even a tank mix requires essentially constant agitation to prevent the pelargonic acid from separating out. Fourth, pelargonic acid is difficult to formulate in a concentrate, therefore, compositions of glyphosate and pelargonic acid are typically sold in dilute “ready-to-use” formulations.

U.S. Pat. No. 5,196,044 discloses herbicidal compositions comprising, for example, glyphosate that are claimed to reduce the time required for systemic phytotoxic symptoms to appear on the target weed. These herbicidal compositions comprise a first ingredient comprising a fatty acid or mixture of fatty acids such as pelargonic acid, also known as nonanoic acid, (the active ingredient in the contact herbicide SCYTHE® and a second ingredient selected from a group of herbicides including glyphosate and paraquat. Scythe® has been observed to rapidly burn plant foliage. A too rapid burn may not allow for the complete translocation of glyphosate throughout the plant. As a result, the plant may later recover and continue growing.

Compositions comprising glyphosate are generally formulated with one or more surfactants to enhance their effectiveness for foliar application. When water is added to a composition formulated with surfactants, the resulting sprayable composition more easily and effectively covers the foliage (e.g., the leaves or other photosynthesizing organs) of plants. Glyphosate salts, for example, have been formulated with surfactants such as polyoxyalkylene-type surfactants including, among other surfactants, polyoxyalkylene alkylamines. Commercial formulations of glyphosate herbicide marketed under the trademark ROUNDUP® have been formulated by Monsanto with such a polyoxyalkylene alkylamine, in particular a polyoxyethylene tallowamine, identified as MON 0818. Glyphosate similarly has been formulated with polyoxyalkylene polysiloxane surfactants, in particular polyoxyethylene trisiloxane surfactants, such as the commercial organosilicone surfactant Silwet® L-77, available from Crompton Corporation. Among the numerous studies of the foliar uptake of glyphosate herbicide combined with Silwet® L-77 are those reported by Field & Bishop in Pesticide Science, 1988, Vol. 24, pp. 55-62; Stevens et al. in Pesticide Science, 1991, Vol. 33, pp. 371-82; Gaskin & Stevens in Pesticide Science, 1993, Vol. 38, pp. 185-92; and Gaskin & Stevens in Pesticide Science, 1993, Vol. 38, pp. 193-200. An extensive review of 160 references relating to the use of organosilicones as adjuvants for agrochemicals was provided by Stevens in Pesticide Science, 1993, Vol. 38, pp. 103-22. In fact, so many studies are reported in this area that OSi Specialties has published a Bibliography of Silwet® Organosilicone Surfactants As Agricultural Adjuvants (1996), which is indexed for computer searching. This reference lists hundreds of published studies of commercial organosilicone surfactants in agricultural applications. This bibliography is available to the public through the publisher's office in Tarrytown, N.Y.

WO 98/35561 discloses aqueous herbicidal compositions useful for controlling woody plants when applied to the bark. These compositions comprise glyphosate and a surfactant composition that comprises one or more polyoxyalkylene trisiloxane surfactants and one or more glycols or glycol ethers.

WO 97/23281 discloses surfactant blends comprising organosilicone compounds and a water-soluble surfactant characterized by hydrophobic groups having from about 4 to about 12 atoms. These surfactant blends are useful as spreading agents for the delivery of agriculturally active ingredients such as herbicides.

EP 0 483 095 A2 discloses aqueous compositions comprising glyphosate, the organosilicone SILWET L-77®, and either propylene glycol, dipropylene glycol or polyethylene glycol.

EP 0 531 269 A2 discloses aqueous compositions comprising glyphosate, the organosilicone SILWET L-77®, and an acetylenic diol.

Herbicidal compositions comprising the herbicide dihydrodipyrido(1,2-a:2′,1′-c)pyrazinediium or derivatives thereof (“diquat”) or another bipyridilium, paraquat, also are useful for suppressing the growth of or killing unwanted grasses, weeds, and the like. This contact herbicide typically is applied to the foliage of the target plant and causes rapid disruption of plant cell membranes. It primarily is used as a herbicide to control weeds in noncrop and aquatic areas. Visual symptoms that a plant has been treated with diquat typically appear within 1 to 3 days of application, depending on environmental conditions.

Herbicidal compositions comprising diquat may comprise one or more surfactants. For example, U.S. Pat. No. 5,665,679 discloses compositions containing diquat dibromide and organosilicone surfactants such as Kinetic™, an organosilicone surfactant available from Setre Chemical.

U.S. Pat. Nos. 5,561,099 and 5,658,852 disclose an oil-based agricultural adjuvant comprising an organosilicone compound and a carrier oil. The adjuvant can be used as a spreading agent in combination with herbicides including, but not limited to, glyphosate and diquat.

U.S. Pat. No. 5,504,054 discloses a group of low foaming, superspreading trisiloxane silicone surfactants useful in aqueous spray mixtures comprising herbicides including, but not limited to, glyphosate and diquat.

U.S. Pat. No. 5,558,806 discloses a polyalkyleneoxide polysiloxane surfactant useful as an adjuvant for dispersing, wetting, spreading, and enhancing the efficacy of a herbicide, including, but not limited to, glyphosate and diquat.

U.S. Pat. No. 5,536,700 discloses herbicidal compositions comprising an aryl-5-haloalkylpyrazole and glyphosate, diquat, paraquat or other herbicides.

U.S. Pat. No. 5,532,205 describes herbicidal compositions containing glyphosate, paraquat or diquat, and a photosystem II inhibitor herbicide. The composition is said to provide early burndown symptoms without excessive reduction in regrowth control as compared to a herbicidal composition containing glyphosate and paraquat or diquat. A composition containing glyphosate and diquat or paraquat in a weight ratio of 20:1 is reported to have produced some early burndown symptoms at the cost of long term or regrowth control. A composition containing significantly less diquat or paraquat is said to provide little by way of visible early burndown symptoms.

Chinese Patent Publication No. 1232614 is said to describe a herbicidal composition containing 41% IPA glyphosate salt and paraquat in a ratio of glyphosate salt to paraquat cation of 25:1 to 2.5:1.

It is an object of the present invention to provide novel herbicidal compositions of glyphosate, a bipyridilium (such as diquat or paraquat) and a surfactant that is of a type and present in a concentration sufficient to allow the plant to uptake a herbicidally effective amount of the glyphosate prior to the substantial onset of bipyridilium induced leaf damage that would prevent or severely reduce further uptake of glyphosate by the plant. Use of such novel compositions for the control of unwanted plants provides rapid bipyridilium symptomology (e.g. rapid burndown) yet with the long term control expected of glyphosate based herbicides.

It is a further object of the invention to provide concentrate liquid and particulate solid formulations of glyphosate, a bipyridilium, and suitable surfactant. Such concentrates can be employed to easily prepare the novel herbicidal compositions of the present invention. A still further object of the present invention is to provide a method of controlling or killing unwanted plants by utilizing the novel herbicidal compositions of the present invention.

SUMMARY OF THE INVENTION

In one aspect, the invention comprises a herbicidal composition useful for controlling vegetation, the composition comprising (a) glyphosate or a herbicidal derivative thereof; and (b) a bipyridilium, such as diquat or paraquat, or a herbicidal derivative thereof; and (c) a suitable surfactant composition comprising one or more surfactant(s). When applied to target foliage the herbicidal composition is characterized by more rapid initial burndown than treatment with glyphosate alone but with comparable long term control.

The herbicidal compositions of the invention can be prepared on site by the end-user shortly before application to the foliage of the vegetation to be killed or controlled by mixing in aqueous solution a glyphosate containing composition; a bipyridilium containing composition, and a suitable surfactant. Such compositions are typically referred to as “tank-mix” compositions.

Alternatively, the compositions of the invention may be provided to the end-user already formulated, either at the desired dilution for application (“ready to use” compositions) or requiring dilution, dispersion, or dissolution in water by the end-user (“concentrate” compositions). Such preformulated concentrates can be liquids or particulate solids.

Suitable surfactant compositions useful in the present inventions are of a type and present in a concentration sufficient to allow the plant to uptake a herbicidally effective amount of the glyphosate prior to the substantial onset of bipyridilium induced leaf damage that would prevent or severely reduce further uptake and translocation of glyphosate by the plant. Particularly preferred surfactants are of the “superspreading” or “superwetting” type described in more detail herein.

An additional aspect of the invention comprises a method for preparation of the particulate solid concentrates of the invention.

A method of use of the herbicidal compositions of the invention for controlling the growth and/or proliferation of unwanted plants is also provided.

DETAILED DESCRIPTION OF THE INVENTION

According to the present invention, herbicidal compositions containing glyphosate, a bipyridilium and a suitable surfactant are provided that allow for rapid uptake by the target plant, early visual symptoms of plant treatment, and control of a broad spectrum of plant species. The following discussion sets forth in detail the compositions and methods of the present invention, through which good control of growth and proliferation of plants is achieved by foliar application of a herbicidal composition comprising glyphosate, a bipyridilium, and one or more suitable surfactants, as more fully described below.

These compositions further provide other advantages in addition to early visual symptoms of treatment. For example, the novel compositions enhance the potency of the bipyridilium applied. As a result, lower application rates can be used for the bipyridilium and/or the surfactants applied without a loss of effectiveness of plant control.

In addition, the novel compositions can be prepared as spray compositions such as ready-to-use or tank mixes or from concentrates. These concentrates can be either liquid or a particulate solid. Additionally, both glyphosate and diquat separately have aquatic clearance, i.e. are approved for use on foliage in water. Further, the novel compositions of the invention provide better long term control and less regrowth than glyphosate-nonanoic acid compositions.

The compositions of the present invention comprise at least two herbicides (glyphosate and a bipyridilium), and at least one surfactant. A first component of the compositions of the present invention is N-phosphonomethylglycine (“glyphosate”), a salt, adduct or ester thereof, or a compound which is converted to glyphosate in plant tissues or which otherwise provides glyphosate ion. The term “glyphosate” when used herein is to be understood to encompass such derivatives unless the context requires otherwise.

Glyphosate salts that can be used according to this invention include but are not restricted to alkali metal salts, for example the mono-, di-, and trisodium salts and the mono-, di-, and tripotassium salts; monoammonium and diammonium salts; alkylamine salts, for example C₁₋₁₆ alkylamine salts such as the dimethylamine and isopropylamine salts; alkylammonium salts, for example C₁₋₁₆ alkylammonium salts such as the dimethylammonium and isopropylammonium salts; alkanolamine salts, for example C₁₋₁₆ alkanolamine salts such as the monoethanolamine salt; alkylsulfonium salts, for example the trimethylsulfonium salt; sulfoxonium salts; and mixtures thereof. The herbicidal compositions sold by Monsanto Company as the ACCORD® herbicide contain the monoisopropylamine (“IPA”) salt of N-phosphonomethylglycine. The herbicidal compositions sold by Monsanto Company as ROUNDUP GEOFORCE® contain the monosodium salt of N-phosphonomethylglycine. The herbicidal compositions sold by Monsanto Company as ROUNDUP FULL® and ROUNDUP MAX® contain the monoethanolamine salt of glyphosate. The herbicidal compositions sold by Syngenta Corporation as TOUCHDOWN® contain the trimethylsulfonium salt of N-phosphonomethylglycine and TOUCHDOWN IQ® contains the diammonium salt of N-phosphonomethylglycine. Especially preferred glyphosate salts include the potassium salt, isopropylamine salt, ammonium salt, monoethanolamine salt, and trimethylsulfonium salt. The herbicidal properties of N-phosphonomethylglycine and its derivatives were first discovered by Franz, then disclosed and patented in U.S. Pat. No. 3,799,758, issued Mar. 26, 1974. A number of herbicidal salts of N-phosphonomethylglycine were patented by Franz in U.S. Pat. No. 4,405,531, issued Sep. 20, 1983. The disclosures of both of these patents are hereby incorporated by reference.

Various salts of N-phosphonomethylglycine are commercially significant in part because they are water soluble. Many of the salts listed immediately above are highly water soluble, thereby allowing for highly concentrated solutions that can be diluted at the site of use. In accordance with the methods of this invention as they pertain to glyphosate herbicide, a solution containing a herbicidally effective amount of glyphosate and other components in accordance with the invention is applied to foliage of plants.

The relative amount of glyphosate present in a contemplated herbicidal composition, particulate solid concentrate, or liquid concentrate will vary depending upon many factors including the plant species to be controlled and the method of application. The glyphosate concentration present in the herbicidal compositions of the invention is sufficient to provide at least 70% control of plant regrowth within 50 days after application of the composition to a plant, and more preferably at least 75%, 80% or 85% control or more within 50 to 55 days after application to the plant.

A bipyridilium is the second component of the compositions of the present invention. Bipyridiliums are the general class of herbicides that include diquat and paraquat. Compounds in this class are characterized by very rapid symptomology. It is believed that the rapid symptomology of the bipyridiliums is a result of their ability to react with photosynthetic mechanisms in plants. The production of superoxides and hydrogen peroxides leads to massive disruption of cells and their physiological processes in any tissues that are contacted. The mode of action of diquat and other members of this class is described in the Herbicide Handbook of WSSA, 7^(th) Edition, 1994. Both diquat and paraquat are tightly bound to soil.

The preferred bipyridilium present in the herbicidal compositions of the present invention is Diquat [6,7-dihydrodipyrido (1,2-a:2′,1′-c)pyrazinediium], a salt or adduct thereof, or a compound which otherwise provides the diquat cation. The term “diquat” when used herein is to be understood to encompass such derivatives unless the context requires otherwise. Other commercial names for diquat include Aquacide™, Dextrone™, Reward®, Reglone®, and Weedtrine D™. Diquat salts that can be used according to this invention include but are not restricted to halide salts, for example the dichloride, difluoride and dibromide salts; and mixtures thereof. For example, and not by way of limitation, Syngenta Corporation sells the dibromide salt of dihydrodipyrido (1,2-a:2′,1′-c)pyrazinediium (“diquat dibromide”) under the name REWARD® or REGLONE® in the form of a composition comprising 37.3% diquat dibromide and 62.7% inert ingredients wherein two pounds of diquat cation are found in a solution having 3.73 pounds of diquat dibromide per gallon. The herbicidal properties of diquat and its derivatives were disclosed on pages 108-110 of WSSA Herbicide Handbook, 1994 (7^(th) Edition) and patented in British Patent 785,732 (1955). The disclosures of both of these references are hereby incorporated by reference.

Salts of diquat are commercially significant in part because they are water soluble. The salts listed immediately above are highly water soluble, thereby allowing for highly concentrated solutions that can be diluted at the site of use. In accordance with the methods of this invention, a herbicidal composition containing glyphosate, diquat, surfactant and optionally other components in accordance with the invention is applied to foliage of plants.

The relative amount of diquat present in a contemplated herbicidal spray composition, particulate solid concentrate, or liquid concentrate varies depending upon many factors including the plant species to be controlled and the method of application. The mixtures or coformulations of the present invention likewise may employ another herbicide in addition to glyphosate and diquat, such as glufosinate and/or paraquat.

In lieu of diquat, a less preferred bipyridilium that may be used is 1,1′-Dimethyl-4,4′-bipyridinium dichloride (paraquat dichloride), a salt or adduct thereof, or a compound which otherwise provides the paraquat cation. The term “paraquat” when used herein is to be understood to encompass such derivatives unless the context requires otherwise. Other commercial names for paraquat include Crisquat™, Cyclone™, Dexuron™, Gramoxone Extra™, Herbaxone™, Ortho™ Weed and Spot Killer and Sweep™. Paraquat has been formulated with other herbicides, including Simazine and diquat dibromide. The dimethyl sulfate salt of paraquat has been commercialized. Paraquat has been widely used for weed control. It also has been employed as a crop desiccant and defoliant, and as a terrestrial herbicide.

The relative amount of paraquat present in a contemplated herbicidal spray composition, particulate solid concentrate or liquid concentrate varies depending upon many factors including the plant species to be controlled and the method of application. The mixtures or coformulations of the present invention likewise may employ another herbicide in addition to glyphosate and paraquat, such as glufosinate and/or diquat.

The bipyridilium concentration present in the herbicidal compositions of the invention is sufficient to provide visual symptoms of herbicidal treatment within 3 days after application of the composition to a plant, and more preferably within 2 days or 24 hours after application to the plant. However, the bipyridilium concentration is also such that it is not substantially antagonistic to the herbicidal activity of the glyphosate within the herbicidal composition. The bipyridilium concentration present in the herbicidal compositions of the invention is sufficient to provide visual symptoms of herbicidal treatment within 3 days after application of the composition to a plant, and more preferably within 2 days or 24 hours after application to the plant. However, the bipyridilium concentration is also such that it is not substantially antagonistic to the herbicidal activity of the glyphosate within the herbicidal composition.

The surfactant component of the composition of the present invention when applied with the above-mentioned herbicidal components of the invention is of the type and present in a sufficient concentration to allow the plant to uptake and translocate a herbicidally effective amount of glyphosate prior to the substantial onset of bipyridilium induced leaf damage that would prevent or severely reduce further uptake and translocation of glyphosate by the plant. One way to accomplish this is to provide more intimate contact between the applied herbicidal composition and the microtopographically rough surface of the plant, for example by flattening the contact angle of the composition, so as to permit the composition to spread into crevices and pores in the plant. However, other modes of enhancement are also possible. For example, the surfactant composition should preferably also enhance sticking or adhesion to a plant surface when used in aqueous solution, and it should allow the solution to dry on a time scale that is effective to permit penetration. It has been found that surfactant compositions containing either polyoxyalkylene trisiloxane surfactants, with optional additional ingredients, or certain combinations of a polyoxyalkylene trisiloxane surfactant and one or more glycols, with optional additional ingredients, can meet these requirements. It has also been found that surfactant compositions including alkoxylated alkylamines, alkoxylated etheramines or alkoxylated etheramine oxides in combination with other surfactants can meet these requirements.

Various surfactants have been found to be effective in formulating herbicidal compositions and concentrates of the invention, particularly in formulating compositions and concentrates containing potassium, ammonium or diammonium glyphosate.

wherein R₁ is a straight or branched chain hydrocarbon having from about 6 to about 22 carbon atoms, m is about 0 to about 10, R₂ is independently C₁-C₄ alkylene, R₃ groups are independently C₁-C₄ alkylene, R₅ is independently C₁-C₄ alkylene, and x and y are average numbers such that x+y is about 2 to about 60, q is 0 or 1, and r is 0 or 1.

Preferred alkoxylated quaternary etheramines are represented by the following structural formula:

wherein R₁ is a straight or branched chain hydrocarbon having about 6 to about 22 carbon atoms, m is about 0 to about 10, R₂ is independently C₁-C₄ alkylene, R₃ groups are independently C₁-C₄ alkylene, x and y are average numbers such that x+y is 0 to about 60, R₄ is C₁-C₄ alkyl, R₅ is independently C₁-C₄ alkylene, q is 0 or 1, r is 0 or 1, and A⁻ is an agriculturally acceptable anion.

Preferred alkoxylated etheramine oxide surfactants are represented by the following structural formula:

wherein R₁ is a straight or branched chain hydrocarbon having from about 6 to about 22 carbon atoms, m is about 0 to about 10, R₂ is independently C₁-C₄ alkylene, R₃ groups are, independently C₁-C₄ alkylene, R₅ is independently C₁-C₄ alkylene, q is 0 or 1, r is 0 or 1, and x and y are average numbers such that x+y is about 2 to about 60.

The straight or branched chain hydrocarbon having from about 6 to about 22 carbon atoms is preferably an alkyl, aryl, or alkylaryl group. Aryl groups, if present in R₁ have 5-7, preferably 6 carbon atoms and may or may not be substituted. The alkyl portion in any alkylaryl group comprising R₁ has 1-16 carbon atoms. Such an alkylaryl group could be alkylphenyl, for example, nonylphenol.

However, in preferred surfactants of the invention R₁ is a straight or branched chain alkyl group having about 8 to about 18, for example about 10-15 carbon atoms, and are derived from the corresponding alcohol. For example, the alkyl group may be naturally derived, from coconut or tallow, for example, or may be derived from a synthetic alcohol such as isodecyl, isotridecyl, linear C₁₂-C₁₄ or octadecyl alcohols.

The R₂ substituent closest to the nitrogen atom (the proximal R₂ group) is preferably a linear propylene (—CH₂CH₂CH₂—), isopropylene (—CH₂CH(CH₃)—) or ethylene (—CH₂CH₂—) group. Preferred examples in which the proximal R₂ group is linear propylene have m=1. Where the proximal R₂ group is isopropylene or ethylene, m is preferably in the range from about 1 to about 5, most preferably from about 2 to about 3, and all R₂ groups are the same.

In quaternary etheramines of the invention, R₄ is preferably methyl and A- is preferably a halide, for example chloride or bromide. A- can also be a phosphate or a sulfate ion, or alternatively may be a glyphosate ion or may be contributed by an anionic surfactant included with the etheramine in the formulation. It will be recognized by those skilled in the art that at low pH such as may well exist in a glyphosate formulation, tertiary etheramines will most likely be protonated at the nitrogen atom and may be associated with a counterion. In these cases the tertiary etheramine is best represented by the chemical structure shown above for a quaternary etheramine with the exception that R4 is hydrogen. The counterion A- in a low pH glyphosate formulation comprising a tertiary amine will most likely be glyphosate itself.

Representative surfactants of the type mentioned above are described in U.S. Pat. Nos. 5,703,015, 5,750,468 and 5,389,598, the entirety of each being incorporated herein by reference.

Preferred are glycols having 4 or more carbon atoms. Of these, 2-methyl-1,3-propanediol and 1,4-butanediol are more preferred glycols. A blend or mixture of several glycols may be used, in which case the total amount of all glycols present is as above. In such a case, it is preferred that at least one of the glycols in the blend be a C₄ or higher glycol, especially 2-methyl-1,3-propanediol or 1,4-butanediol. In another embodiment, the surfactant composition contains about 50% to about 80% by weight of 2-methyl-1,3-propanediol, 1,4-butanediol or a mixture thereof and about 5% to about 30% by weight of propylene glycol.

A composition of the invention that includes both the glycol or glycol ester and the polysiloxane, such as polyoxyalkylene trisiloxane, exhibits increased penetration of the herbicidal composition into or through the plant, under certain conditions, namely hot, dry conditions.

Other nonionic surfactants may likewise be found useful, including without restriction polyoxyethylene polyoxypropylene block copolymers and alkyl polyglucosides. Cationic, anionic or amphoteric surfactants may also be included if desired.

In one embodiment of the invention, the herbicidal compositions include at least one nonionic surfactant and at least one cationic surfactant such as those described herein. Such surfactant combinations are described in U.S. Pat. No. 5,998,332, which is incorporated herein by reference.

The surfactant compositions typically are intended for mixing with a water soluble herbicide composition. It is preferred that there be substantially no water present in the surfactant composition.

A surfactant composition of the invention comprises any combination of the surfactants as described above. The surfactant composition is particularly preferred for use in formulating compositions or concentrates containing potassium, di-ammonium, ammonium, sodium, monoethanolamine, n-propylamine, methylamine, ethylamine, hexamethylenediamine, dimethylamine and/or trimethylsulfonium glyphosate, and diquat or paraquat. The surfactant composition can be incorporated into a composition or concentrate comprising any combination of these glyphosate salts and diquat and/or paraquat.

The density of any glyphosate-containing formulation of the invention is preferably at least 1.050 grams/liter, more preferably at least about 1.055, 1.060, 1.065, 1.070, 1.075, 1.080, 1.085, 1.090, 1.095, 1.100, 1.105, 1.110, 1.115, 1.120, 1.125, 1.130, 1.135, 1.140, 1.145, 1.150, 1.155, 1.160, 1.165, 1.170, 1.175, 1.180, 1.185, 1.190, 1.195, 1.200, 1.205, 1.210, 1.215, 1.220, 1.225, 1.230, 1.235, 1.240, 1.245, 1.250, 1.255, 1.260, 1.265, 1.270, 1.275, 1.280, 1.285, 1.290, 1.295, 1.300, 1.305, 1.310, 1.315, 1.320, 1.325, 1.330, 1.335, 1.340, 1.345, 1.350, 1.355, 1.360, 1.365, 1.370, 1.375, 1.380, 1.385, 1.390, 1.395, 1.400, 1.405, 1.410, 1.415, 1.420, 1.425, 1.430, 1.435, 1.440, 1.445, or 1.450 grams/liter.

As further discussed herein, other additives, adjuvants, or ingredients may be introduced into the formulations of the present invention to improve certain properties of the resulting formulations. Although the formulations of the present invention generally show good overall stability and viscosity properties without the addition of any further additives, the addition of a solubilizer (also commonly referred to as a cloud point enhancer or stabilizer) can significantly improve the properties of the formulations of the present invention. Suitable solubilizers for use with the novel formulations of the present invention include, for example, cocoamine (Armeen C), dimethylcocoamine (Arquad DMCD), cocoammonium chloride (Arquad C), PEG 2 cocoamine (Ethomeen C12), PEG 5 tallowamine (Ethomeen T15), and PEG 5 cocoamine (Ethomeen C1 5), all of which are manufactured by Akzo Nobel (California).

Additionally, it has been found that the addition of a C₄ to C₁₆ alkyl or aryl amine compound, or the corresponding quaternary ammonium compound, greatly enhances the compatibility of certain glyphosate salts (e.g., potassium or isopropylamine) with surfactants that otherwise exhibit low or marginal compatibility at a given glyphosate loading. Suitable alkyl or aryl amine compounds may also contain 0 to about 5 ethylene oxide groups. Preferred alkylamine compounds include C₆ to C₁₂ alkylamines having 0 to 2 ethylene oxide groups. Similarly, etheramine compounds having 4 to 12 carbons and 0 to about 5 ethylene oxide groups, as well as the corresponding quaternary ammonium compounds, also enhance the compatibility of such formulations. In one embodiment, the compounds which enhance the compatibility of such surfactants include amines or quaternary ammonium salts having the formula:

wherein R¹ is linear or branched alkyl or aryl having from about 4 to about 16 carbon atoms, R² is hydrogen, methyl, ethyl, or —(CH₂CH₂O)_(x)H, R³ is hydrogen, methyl, ethyl, or —(CH₂CH₂O)_(y)H wherein the sum of X and y is not more than about 5; R⁴ is hydrogen or methyl; R⁶ in each of the n (R⁶O) groups is independently C₂-C₄ alkylene; R⁵ is hydrocarbylene or substituted hydrocarbylene having from 2 to about 6 carbon atoms; and A- is an agriculturally acceptable anion.

Also provided by the present invention is a herbicidal method comprising diluting with a suitable volume of water a herbicidally effective volume of a concentrate as provided herein to form an application mixture, and applying the application mixture to foliage of a plant or plants.

When a maximum or minimum “average number” is recited herein with reference to a structural feature such as oxyethylene units or glucoside units, it will be understood by those skilled in the art that the integer number of such units in individual molecules in a surfactant preparation typically varies over a range that can include integer numbers greater than the maximum or smaller than the minimum “average number.” The presence in a composition of individual surfactant molecules having an integer number of such units outside the stated range in “average number” does not remove the composition from the scope of the present invention, so long as the “average number” is within the stated range and other requirements are met.

By “storage-stable,” in the context of a liquid concentrate of the invention, is meant not exhibiting phase separation on exposure to temperatures up to about 50° C. for 14-28 days, and preferably not forming crystals of glyphosate or salt thereof on exposure to a temperature of about 0° C. for a period of up to about 7 days (i.e., the composition must have a crystallization point of 0° C. or lower). For aqueous solution concentrates, high temperature storage stability is often indicated by a cloud point of about 50° C. or more. Cloud point of a composition is normally determined by heating the composition until the solution becomes cloudy, and then allowing the composition to cool, with agitation, while its temperature is continuously monitored. A temperature reading taken when the solution clears is a measure of cloud point. A cloud point of 50° C. or more is normally considered acceptable for most commercial purposes for a glyphosate aqueous solution concentrate. Ideally the cloud point should be 60° C. or more, and the composition should withstand temperatures as low as about −10° C. for up to about 7 days without crystal growth, even in the presence of seed crystals of the glyphosate salt.

Additional ingredients, including other surfactants for example, may also be utilized in the present invention. It often proves desirable to employ additional surfactants in order, for example, to moderate the spreading properties imparted to the composition by a super spreading surfactant.

Another ingredient that can optionally be added to the compositions of the present invention to further improve the herbicidal effectiveness and related herbicidal properties is a dicarboxylic acid or salt of a dicarboxylic acid. Suitable dicarboxylic acids that may be added to the compositions as described herein include, for example, oxalic acid, malonic acid, succinic acid, glutaric acid, maleic acid, adipic acid, and fumaric acid, and combinations or mixtures thereof, with oxalic acid being preferred. Also, in addition to, or in place of the dicarboxylic acid, salts of the aforementioned dicarboxylic acids may be incorporated into the compositions of the present invention to improve herbicidal performance. Suitable salts include, for example, alkali metal salts such as potassium salts, alkanolamine salts and lower alkylamine salts. Preferred salts include potassium oxalate, dipotassium oxalate, sodium oxalate, disodium oxalate, diammonium oxalate, diethanolamine oxalate, dimethylamine oxalate, alkanolamine salts of oxalic acid, and lower alkylamine salts of oxalic acid. Compositions containing a dicarboxylic acid such as oxalic acid or a dicarboxylic acid salt such as potassium oxalate, typically contain a sufficient amount of dicarboxylic acid/dicarboxylic acid salt to enhance the resulting efficacy of the composition. Typically, the weight ratio of total surfactant to dicarboxylic acid/dicarboxylic acid salt may be from about 1:1 to about 50:1, more preferably 5:1 to 40:1 and most preferably from about 5:1 to about 20:1. This ratio of total surfactant to dicarboxylic acid/dicarboxylic acid salt significantly enhances the herbicidal performance of the resulting composition.

While the herbicidal compositions of the invention include water and water-soluble ingredients, the present invention encompasses compositions additionally containing one or more oils, which may be of vegetable origin (such as methylated vegetable oils) or petroleum derived, together with any standard formulation ingredients such as emulsifiers that might be used to stabilize the oil in the aqueous composition.

The herbicidal compositions of the invention can be formulated as spray compositions or concentrates. The term herbicidal spray composition is used herein to indicate a herbicidal composition that is ready for application to target foliage. Such a herbicidal composition can be obtained by dilution of a liquid concentrate with water, or dissolution or dispersion in water of a dry (e.g. granular, powder, tablet or briquette) formulation such as a particulate solid concentrate which may contain small amounts of water. Spray compositions include tank mixes and ready-to-use formulations.

Herbicidal spray compositions of the present invention typically can be made with a glyphosate concentration from about 2 to about 36 grams acid equivalent per liter, preferably from about 4 to about 18 grams acid equivalent per liter, more preferably from about 6 to about 11 grams acid equivalent per liter.

The weight ratio of glyphosate to bipyridilium in the herbicidal spray compositions of the invention preferably is between about 20:1, 21:1, 22:1, 23:1, 24:1, 25:1, 26:1, 27:1, 28:1, 29:1, 30:1, or 35:1 and about 100:1. The weight ratio of glyphosate to surfactant in the herbicidal compositions of the invention preferably is between about 0.5:1, 0.6:1, 0.7:1, 0.8:1, 0.9:1, 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1 or 8:1 and about 100:1.

The herbicidal spray composition described above can be obtained by dilution of a liquid concentrate with water, or dissolution, dispersion or suspension in water of a dry (e.g. granular, powder, tablet or briquette) formulation, such as a particulate solid concentrate which may contain small amounts of water.

The particulate solid concentrates of the invention yield aqueous solutions when dissolved in water which upon proper dilution are to be used in accordance with the method of the present invention. The particulate solid concentrates of the present invention are storage stable.

This particulate solid concentrate comprises by weight about 50% to 95% glyphosate acid (a.e.) or a herbicidally acceptable salt or ester thereof (a.i.), preferably from about 60% to 90%, more preferably from about 70% to about 85%; or about 65% to 85%; 0.5% to 3% by weight of a bipyridilium (c.e.), preferably from about 1% to 2.5% c.e., more preferably from about 1.3% to 2% c.e.; 5% to 40% by weight of a surfactant, preferably from 7% to 30%, more preferably 10% to 25%; 0 to 1% by weight of an antioxidant, preferably from about 0.2% to 0.8%, more preferably from about 0.3% to 0.5%; 0 to 2.0% by weight of antifoam agent, preferably 0.2% to 1.5%, more preferably from about 0.6% to 1.0%.

Thus, a preferred embodiment contains about 60% to 90% by weight (a.i.) of an alkali metal, ammonium, C₁₋₁₆ alkylammonium, C₁₋₁₆ alkanolammonium or C₁₋₁₆ alkylsulfonium salt of glyphosate; and about 1% to 2.5% by weight of a bipyridilium; about 7% to 30% by weight of one or more surfactant(s); about 0.2% to 0.8% by weight of antioxidant; and about 0.2% to 1.5% by weight antifoam agent.

A more preferred embodiment contains about 65% to 85% by weight (a.i.) of an ammonium or sodium salt of glyphosate; about 1.3% to 2% by weight (c.e.) of a salt of diquat; about 10% to 25% by weight polysiloxane surfactant; about 0.3% to 0.5% by weight antioxidant; and 0.6% to 1.0% by weight antifoam agent.

Therefore, particulate solid concentrates of the present invention typically can be made with weight ratios of about 1:1 to 100:1 glyphosate (a.e.) to bipyridilium (c.e.), preferably from about 22:1 to 90:1, more preferably from about 40:1 to about 50:1. Further, the particulate solid concentrates can be made with weight ratios of about 1:1 to about 40:1 glyphosate (a.e.) to surfactant, preferably from about 1.5:1 to 15:1, more preferably from about 2:1 to about 6:1. The particulate solid concentrates can also be made with weight ratios of about 0.013:1 to 11:1 bipyridilium (c.e.) to surfactant, preferably from about 0.018:1 to 0.5:1, more preferably from about 0.02:1 to about 0.15:1.

The antioxidant is used to prevent the formation of nitrosamine. Examples include, but are not limited to ascorbic acid and sodium sulfite. Sodium sulfite is the preferred antioxidant.

Preferably the antifoam agent used is Antifoam™ or Y-14088 Antifoam™, both available from Crompton Corporation. Preferred organosilicone surfactants include, but are not limited to, Silwet L-77™, Silwet 800™ and Breakthru AF-9903™, Breakthru S-240™ organosilicone surfactants.

The particulate solid concentrate of the invention preferably exhibits a dissolution rate of not more than five minutes, more preferably not more than four minutes, three minutes, two minutes or 1 minute.

The particulate solid concentrate is prepared by combining glyphosate, a bipyridilium, and one or more surfactants. Preferably, the particulate solid concentrate is prepared by combining an antioxidant, a salt of glyphosate, antifoam, organosilicone surfactant and a bipyridilium. More preferably, the particulate solid concentrate is prepared by combining sodium sulfite, ammonium glyphosate, antifoam, organosilicone surfactant and diquat. In the more preferred process for preparing the particulate solid concentrate, sodium sulfite is added to a blender containing ammonium glyphosate and mixed. In a separate container, antifoam is added to an amount of an organosilicone surfactant and blended. This surfactant/antifoam mixture is slowly added to the ammonium glyphosate/sodium sulfite mixture. Diquat is then added to the combined mixture and mixed at room temperature. The combined mixture is then processed through an extruder. The resulting extrudate is then dried. The dried composition is further purified to select for particles of a certain size to produce the desired particulate solid concentrate product. The particulate solid concentrate can be prepared by other processes.

A liquid concentrate containing glyphosate can be diluted with water to yield the herbicidal spray composition described above which is ready for application to foliage. The liquid concentrates of the present invention are storage stable.

Preferred salts of glyphosate for use in a liquid concentrate of the invention include the IPA salts of glyphosate, monoethanolamine salt of glyphosate, the ammonium salts of glyphosate and the potassium salts of glyphosate. Commercially available sources of glyphosate include Roundup Ultra®, Roundup UltraMAX®, Ranger®, Roundup Full®, and Super-Roundup®, which are from Monsanto Company. Preferred bipyridiliums include diquat. The weight ratio of glyphosate to bipyridilium in the herbicidal compositions of the invention preferably is between about 26:1, 27:1, 28:1, 29:1, 30:1, 31:1, 32:1, 33:1, 34:1, 35:1, 36:1, 37:1, 38:1, 39:1 or 40:1 and about 100:1.

The liquid concentrate is prepared by combining glyphosate, a bipyridilium, one or more surfactants and water. Preferably, the concentrate is prepared by combining MON 0139, a suitable surfactant, a bipyridilium such as diquat, and water. Concentrates can be prepared by combining commercially available herbicides which include at least one surfactant, a glyphosate salt, a bipyridilium, and water. For example, Roundup Ultra®, Roundup UltraMAX®, Ranger®, Roundup Full® or Super-Roundup® can be mixed with Reglone® and water.

The herbicidal spray composition can be prepared from the liquid concentrate by diluting the liquid concentrate in an appropriate volume of water and agitating as needed. The resulting herbicidal spray composition can then be applied, for example by spraying, to any unwanted vegetation to be killed or controlled. Herbicidal spray compositions can be prepared from particulate solids by dissolving or dispersing the particulate solids in an appropriate volume of water, agitating as needed, and applying to unwanted vegetation. Prepared herbicidal compositions of the present invention containing superspreading surfactants should be used within 24 to 48 hours following preparation, depending upon various conditions.

The herbicidal spray compositions of the present invention are applied as aqueous solutions or dispersions, whether they result from the further dilution of the liquid concentrate or the addition of water to the particulate solid concentrate. The term “aqueous” as used herein is not intended to exclude the presence of some small amount of nonaqueous solvent, so long as the predominant solvent present, other than the glycol or glycol ester component of the surfactant composition, is water. The herbicidal spray compositions included in the present invention can be applied to the foliage of the plants to be treated through any of the appropriate methods that are well known to those having skill in the art.

Herbicidal effectiveness is one of the biological effects that can be enhanced through this invention. “Herbicidal effectiveness,” as used herein, refers to any observable measure of control of plant growth, which can include one or more of the actions of (1) killing, (2) inhibiting growth, reproduction or proliferation, and (3) removing, destroying, or otherwise diminishing the occurrence and activity of plants. The herbicidal effectiveness data set forth herein report “control” as a percentage following a standard procedure in the art which reflects a visual assessment of plant mortality and growth reduction by comparison with untreated plants, made by technicians specially trained to make and record such observations. In all cases, a single technician makes all assessments of percent control within any one experiment or trial. Such measurements are relied upon and regularly reported by Monsanto Company in the course of its herbicide business.

The selection of application rates that are biologically effective for glyphosate is within the skill of the ordinary agricultural scientist. Those of skill in the art will likewise recognize that individual plant conditions, weather and growing conditions, as well as the glyphosate formulation selected, will affect the efficacy achieved in practicing this invention. Useful application rates for glyphosate can depend upon all of the above conditions. With respect to the use of the method of this invention, much information is known about appropriate application rates for glyphosate herbicide. Over two decades of glyphosate use and published studies relating to such use have provided abundant information from which a weed control practitioner can select glyphosate application rates that are herbicidally effective on particular species at particular growth stages in particular environmental conditions.

In general, the herbicidal composition of the present invention is applied to plants at a rate sufficient to give the desired biological effects: control of plant growth and early visual symptoms of treatment. The amount of glyphosate and a bipyridilium applied to plants in combination generally provides a herbicidally-effective amount of herbicide. The amount of glyphosate and a bipyridilium applied to plants further is sufficient to provide early visual symptoms of plant treatment without significantly reducing the desired biological effect of the glyphosate. These application rates are usually expressed as amount of glyphosate per unit area treated, e.g. grams per hectare (g/ha). What constitutes a “desired effect” varies according to the standards and practice of those who investigate, develop, market and use compositions. Typically, the amount of the composition applied per unit area to give 85% control of a plant species as measured by growth reduction or mortality is often used to define a commercially effective rate. Early visual symptoms of treatment generally should appear no later than four days after treatment, preferably no later than three days after treatment, more preferably no later than two days after treatment, and still more preferably no later than one day after treatment.

In the herbicidal composition as applied to the target foliage, for example, the application rate of glyphosate ranges from about 0.5 to about 12 pounds acid equivalent per acre, preferably from about 3.0 to about 9.0, and more preferably from about 4.5 to about 7.5 pounds acid equivalent per acre; the application rate of bipyridilium ranges from about 0.01 to about 0.5 pounds cation per acre, preferably from about 0.025 to about 0.25, and more preferably from about 0.0625 to about 0.15 pounds cation per acre; and the application rate of the surfactant composition ranges from about 0.25 to about 9.0 pounds per acre; preferably from about 0.55 to about 5.5, and more preferably from about 1.0 to about 3.5 pounds per acre.

The herbicidal composition of the present invention can be applied at a carrier volume of between about 20 gallons per acre to about 250 gallons per acre. Preferably, the herbicidal composition of the present invention is applied at between about 50 gallons per acre to about 200 gallons per acre. More preferably, the herbicidal compositions of the present invention are applied at about 75 gallons per acre to about 175 gallons per acre. Still more preferably, the herbicidal compositions of the present invention are applied at between about 80 gallons per acre to about 150 gallons per acre.

Also included in the invention is a method of killing or controlling weeds or unwanted vegetation comprising the steps of diluting the liquid concentrate in a convenient amount of water to form an application mixtureand applying a herbicidally effective amount of the application mixture to the foliage of the weeds or unwanted vegetation. Similarly included in the invention is the method of killing or controlling weeds or unwanted vegetation comprising the steps of diluting a solid particulate concentrate in a convenient amount of water to form an application mixture and applying a herbicidally effective amount of the application mixture to the foliage of the weeds or unwanted vegetation. The application mixture is typically a tank mix.

The formulations of Table 1 were prepared by mixing the components of each formulation specified in Table 1 in water with mild agitation in an amount sufficient to provide the stated application rate based on an application rate of 100 gallons per acre. The resulting tank mix was applied by backpack sprayer using 8008 VS flat fan nozzles calibrated to deliver a spray volume of 100 gallons per acre at a pressure of 12 psi. The herbicidal compositions were applied as post-emergent applications to the foliage of the plants.

At various intervals after treatment, all plants in the test were examined by a single practiced technician to evaluate percent control, which is a visual measurement of the effectiveness of the treatment by comparison with untreated plants. The percent control figures reported represent the average control determined for a sample size of 10-15 treated plants, by comparison with untreated plants. A percent control value of 0% indicates no effect, and a percent control value of 100% indicates that all of the specimens are completely dead.

The preparation and application of the formulations of Examples 2, 3, 4 and 5 was carried out in a manner similar to Example 1 using the components in the proportions reported in those Examples. The preparation and application of the formulations of subsequent Examples 6-14 was conducted in a manner similar to Example 1 with the exception that Formulation A was prepared from a particulate solid concentrate in the manner described in Example 19. Similarly, Formulation B was prepared from a particulate solid concentrate in the manner described in Example 20, Formulation C was prepared from a particulate solid concentrate in the manner described in Example 21, and Formulation D was prepared from a particulate solid concentrate in the manner described in Example 22.

The treatment number(s) listed in each table of the examples corresponds to the formulations listed in the above table. The active ingredient (e.g., herbicide or surfactant) application rate or the active ingredient concentration of the spray composition appears in parentheses following the treatment number. For example, 1(6# ae/A) as in Table 1 refers to the application of 6 lbs. glyphosate a.e. per acre of ROUNDUP PRODRY®.

In a separate glass beaker, 279.6 grams of Silwet 800™ and 12.0 grams of Y-14088 antifoam added to the Silwet 800™ and blended using a stirring rod. This surfactant/antifoam mixture was slowly poured into the dry ingredients in the Hobart blender with the blender set on low speed. 88.8 grams of REWARD® was then added to the mixture and mixed at ambient temperature for 5 minutes. A second batch of material was prepared as above and combined with the first batch. The combined mixture was then processed through a twin screw EXS-60 extruder fitted with a 1.0 mm screen. The resulting extrudate was dried for 10 minutes in a fluid bed dryer at 60 degrees Celsius. The dried composition was passed through a 12 mesh screen to sieve off any agglomerated clumps and placed on a 40 mesh screen to remove any fine materials. Mild agitation is used to promote product flow through the screens. The material on the 40 mesh screen is collected as product and the over and undersize material is discarded. Approximately 1.9 kilograms of product was produced.

Example 26

A test was conducted in Missouri to determine the effectiveness of the herbicide formulations of Tables 37 and 38 for killing or controlling velvetleaf (Abutilon theophrasti, ABUTH) and barnyardgrass (Echinocloa crus-galli, ECHCG). Applications were made in August and evaluations were made at 2 and 17 days after application.
